Hi! Welcome to the world of
Scientific Instruments!
Come on! There are currently 224 scientific instruments on display in 17 cases. Most were used for physics teaching and research at the Old Academy of Lausanne and, since 1890, at the University of Lausanne (UNIL). Each instrument is accompanied by a brief explanatory note in French. The time period covered is approximately from 1775 to 1960.
From the plot, we can find something interesting. Like for the category: Électricité & Magnétisme. While the early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering. Through such people as Alexander Graham Bell, Ottó Bláthy, Thomas Edison, Galileo Ferraris, Oliver Heaviside, Ányos Jedlik, William Thomson, 1st Baron Kelvin, Charles Algernon Parsons, Werner von Siemens, Joseph Swan, Reginald Fessenden, Nikola Tesla and George Westinghouse, electricity turned from a scientific curiosity into an essential tool for modern life.[1]
